21 gru 2023 · When the complex ion with EDTA is formed, the EDTA ligand displaces six aqua ligands at once. Ethylenediamine ligands displace two at a time and ammine ligands displace one at a time. Based on this we would expect [Ni(EDTA)]2 − to be the most stable and [Ni(NH 3) 6]2 + to be the least stable.

23 cze 2023 · According to Le Chatelier's principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. This particular reaction shows a total of 4 mol of gas as reactants and 2 mol of gas as products, so the reaction shifts toward the products side.
13 maj 2023 · The equilibrium constant for the decomposition of CaCO3 (s) to CaO (s) and CO2 (g) is K = [CO2]. At 800°C, the concentration of CO2 in equilibrium with solid CaCO3 and CaO is 2.5 × 10 − 3 M. Thus K at 800°C is 2.5 × 10 − 3 (remember that equilibrium constants are unitless).
10 sie 2021 · Co(OH) 2 @NC cathode delivers a maximal discharging current density nearly 300 mA cm −2 while Pt/C-IrO 2 only reaches 200 mA cm −2 at 0.5 V. The peak power density of Co(OH) 2 @NC (Fig. 5 (c)) is about 148 mW cm −2, significantly larger than the value of Pt/C-IrO 2 (106 mW cm −2).
The H+ (aq) concentration can be increased by adding a source of H+ (aq) - hydrochloric acid, HCl. The H+ (aq) concentration can be decreased by adding a solution of sodium hydroxide, NaOH, which contains the hydroxide ion, OH- (aq). The OH- (aq) reacts with H+ (aq) to form H2O, causing a shift in the equilibrium.
Add 2 drops of 1 M NaOH (note: this will reduce the amount of H + ions – what does this due to the amount of Cr 2 O 7 2- (aq) ions present?). Add 0.1 M Ba +2 (aq) ions drop by drop, until a change is noted.
1 lis 2021 · Using the self-ionization of H 2 O into OH − and H +, reaction (1) can be written with a product H + instead. Both reactions equivalently describe the acidity of a water-absorbed Ti site.
